How to remove CRUD?

Question

Yii

I go to the admin panel, shows a list from the database. View works update works, I click on fish and bad request (#400) pops up WHY ?
public function actionDelete($id)
{
$this->findModel($id)->delete();
return $this->redirect(['index']);
}

Answer 1

Because in CRUD it is worth deleting only by the POST method (look at the generator example, you can see in what format the link should be in order to delete the request). This is made from CSRF attacks.
What to do?
1) Or follow only the link that makes an AJAX delete request (see the standard code after the generator)
2) Remove the behavior VerbFilter, but this is very undesirable, as it reduces the security of the application

Answer 2

You only have post permission for deletion, so links should send a post request.
If you do it through get, then the first search engine will delete everything nafig, as it will follow these links. (if there is open access)

How to do it technically?
